LAN
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.
Ethernet and Wi-Fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token Ring, and AppleTalk.

Laptop
A laptop or laptop computer is a small, portable personal computer (PC) with a “clamshell” form factor, typically having a thin LCD or LED computer screen mounted on the inside of the upper lid of the clamshell and an alphanumeric keyboard on the inside of the lower lid. The clamshell is opened up to use the computer. Laptops are folded shut for transportation, and thus are suitable for mobile use. Its name comes from lap, as it was deemed to be placed on a person’s lap when being used. Although originally there was a distinction between laptops and notebooks (the former being bigger and heavier than the latter), as of 2014, there is often no longer any difference. Today, laptops are commonly used in a variety of settings, such as at work, in education, for playing games, web browsing, for personal multimedia, and general home computer use.
Laptops combine all the input/output components and capabilities of a desktop computer, including the display screen, small speakers, a keyboard, data storage device, sometimes an optical disc drive, pointing devices (such as a touchpad or trackpad), with an operating system, a processor and memory into a single unit. Most modern laptops feature integrated webcams and built-in microphones, while many also have touchscreens. Laptops can be powered either from an internal battery or by an external power supply from an AC adapter. Hardware specifications, such as the processor speed and memory capacity, significantly vary between different types, models and price points.
Design elements, form factor and construction can also vary significantly between models depending on intended use. Examples of specialized models of laptops include rugged notebooks for use in construction or military applications, as well as low production cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountants, or for traveling sales representatives. As the portable computers evolved into the modern laptop, they became widely used for a variety of purposes.

Large-screen television technology developed rapidly in the late 1990s and 2000s. Various thin screen technologies are being developed, but only the liquid crystal display (LCD), plasma display (PDP) and Digital Light Processing (DLP) have been released on the public market. A video display that uses large-screen television technology is called a jumbotron. These technologies have almost completely displaced cathode ray tubes (CRT) in television sales, due to the necessary bulkiness of cathode ray tubes. However, recently released technologies like organic light-emitting diode (OLED) and not-yet released technologies like surface-conduction electron-emitter display (SED) or field emission display (FED) are making their way to replace the first flat screen technologies in picture quality. The diagonal screen size of a CRT television is limited to about 40 inches because of the size requirements of the cathode ray tube, which fires three beams of electrons onto the screen, creating a viewable image. A larger screen size requires a longer tube, making a CRT television with a large screen (50 to 80 inches) unrealistic because of size. The aforementioned technologies can produce large-screen televisions that are much thinner.

Linux
Linux (/ˈlinʊks/ (About this soundlisten) LEEN-uuks or /ˈlɪnʊks/ LIN-uuks[9]) is a family of open-source Unix-like operating systems based on the Linux kernel,[10] an operating system kernel first released on September 17, 1991, by Linus Torvalds.[11][12][13] Linux is typically packaged in a Linux distribution.
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name “GNU/Linux” to emphasize the importance of GNU software, causing some controversy.[14][15]
Popular Linux distributions[16][17][18] include Debian, Fedora, and Ubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise Server. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for servers may omit graphics altogether, or include a solution stack such as LAMP. Because Linux is freely redistributable, anyone may create a distribution for any purpose.

List of genres
This is a list of genres of literature and entertainment (film, television, music, and video games), excluding genres in the visual arts.
Genre is the term for any category of creative work, which includes literature and other forms of art or entertainment (e.g. music)—whether written or spoken, audio or visual—based on some set of stylistic criteria. Genres are formed by conventions that change over time as new genres are invented and the use of old ones are discontinued. Often, works fit into multiple genres by way of borrowing and recombining these conventions.

Literary genre
A literary genre is a category of literary composition. Genres may be determined by literary technique, tone, content, or even (as in the case of fiction) length. They generally move from more abstract, encompassing classes, which are then further sub-divided into more concrete distinctions.[1] The distinctions between genres and categories are flexible and loosely defined, and even the rules designating genres change over time and are fairly unstable.[2]
Much of current classical literary genres starting with the ideologies of Aristotle as outlined in his famous treatises, Rhetoric and Poetics. In the treatise Rhetoric, Aristotle arranges rhetorical literary genres into three categories: the deliberative, forensic, and epideictic.[3] He further categorizes genres of poetry in his treatise Poetics, where he also creates three different genre forms: the epic, tragedy, and comedy.[3] Aristotle’s ideas regarding literary genre were fine-tuned through the work of other scholars. [4]
Genres can all be in the form of prose or poetry. Additionally, a genre such as satire, allegory or pastoral might appear in any of the above, not only as a subgenre (see below), but as a mixture of genres. Finally, they are defined by the general cultural movement of the historical period in which they were composed.
Genre should not be confused with age categories, by which literature may be classified as either adult, young adult, or children’s. They are also not the same as ‘format’, such as graphic novel or picture book sub-genre.

Livestreaming
Livestreaming refers to online streaming media simultaneously recorded and broadcast in real-time. It is often referred to simply as streaming, but this abbreviated term is ambiguous because “streaming” may refer to any media delivered and played back simultaneously without requiring a completely downloaded file. Non-live media such as video-on-demand, vlogs, and YouTube videos are technically streamed, but not live-streamed.
Livestream services encompass a wide variety of topics, from social media to video games to professional sports. Platforms such as Facebook Live, Periscope, Kuaishou, Douyu, bilibili and 17 include the streaming of scheduled promotions and celebrity events as well as streaming between users, as in videotelephony. Sites such as Twitch have become popular outlets for watching people play video games, such as in esports, Let’s Play-style gaming, or speedrunning. Live coverage of sporting events is a common application.
User interaction via chat rooms forms a major component of livestreaming. Platforms often include the ability to talk to the broadcaster or participate in conversations in chat. Many chat rooms also consist of emotes[clarification needed] which is another way to communicate to the livestreamer.

Logical Topology
Logical topology is the arrangement of devices on a computer network and how they communicate with one another. Logical topologies describe how signals act on the network.
In contrast, a physical topology defines how nodes in a network are physically linked and includes aspects such as geographic location of nodes and physical distances between nodes. The logical topology defines how nodes in a network communicate across its physical topology. The logical topology can be considered isomorphic to the physical topology, as vice versa.
Early twisted pair Ethernet with a single hub is a logical bus topology with a physical star topology. While Token Ring is a logical ring topology with a physical star topology.

LTE
In telecommunications, Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported.
https://en.m.wikipedia.org/wiki/LTE_(telecommunication)
LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10.
https://en.m.wikipedia.org/wiki/LTE_Advanced
LTE Advanced Pro (LTE-A Pro, also known as 4.5G, 4.5G Pro, 4.9G, Pre-5G, 5G Project) is a name for 3GPP release 13 and 14. It is the next-generation cellular standard following LTE Advanced (LTE-A) and supports data rates in excess of 3 Gbit/s using 32-carrier aggregation. It also introduces the concept of License Assisted Access, which allows sharing of licensed and unlicensed spectrum.
Additionally, it incorporates several new technologies associated with 5G, such as 256-QAM, Massive MIMO, LTE-Unlicensed and LTE IoT, that allow evolution of existing networks into supporting the 5G standard.

Luxury car
A luxury car is a car that provides increased levels of comfort, equipment, amenities, quality, performance, and status relative to regular cars for an increased price.
The term is subjective and reflects both the qualities of the car and the brand image of its manufacturer.[1] Luxury brands rank above premium brands,[2] though there is no fixed demarcation between the two.
Traditionally, most luxury cars were large vehicles, though smaller sports-oriented models were always produced. “Compact“ luxury vehicles such as hatchbacks, and off-road capable sport utility vehicles, are relatively modern trends.[1]
